What are recommended game engines to use for a dual-screen application with:

• One screen will be a PC/Windows screen for set up of the visualizations and parameters - ideally a classic WPF or Winform application.
• One screen will be a full-screen window controlled by the game engine.
• The graphics will lean heavily towards visualization of particle systems (comprising particles, clouds, fog, rays, embers, etc.)
• The application is meant for eye candy, not scientific visualization, so the higher-quality the graphics, the better. (It'd be awesome if I could render output from Trapcode in real time, and control the parameters in real time.)
